Add the 'edited' event type to the milestone trigger in the
call_sync_milestone_to_jira workflow. This ensures that when a
milestone is renamed (e.g. to match a Jira release version), the
sync workflow fires and updates the corresponding Jira release.
Previously only milestone created/closed/deleted events triggered
the sync, so edits to milestone titles were silently ignored.
